Was A Greenhouse Gas Effect Responsible For Ancient Water On Mars?

November 25, 2013

Scientists are constantly trying to determine how water could have once flowed on the Red Planet. A new theory suggests that a greenhouse gas effect could have created favorable conditions for water on Mars nearly 4 billion years ago. Scientists are suggesting that the combination of molecular hydrogen, carbon dioxide, and water could have created a greenhouse effect that would have produced temperatures warm enough to allow for the existence of liquid water. They say that this water would have formed the Nanedi Valles, which is basically the Martian Grand Canyon. There are several cold model theories that attempt to explain the formation of Martian valleys but the researchers in this study say they hope that their new warm model will get others to reconsider their positions.
